For example, the stage direction position detection circuit 69 detects the count value of the counter R2OO. When it is j, the count content is the column direction dimension of 200T! A stage information signal of Rm is output. Furthermore, when the creation start key 55 is pressed and a creation start signal is given with the pen switch 24 set to the start position 42 of the machine frame 13, the writing control circuit 61 changes the position in the knitting width direction. A reset signal is given to the detection circuit 68 and the column direction position detection circuit 69 to reset the contents of the respective counters to RO, and a clear signal is given to the creative pattern memory 64 to clear the stored contents. It's becoming like that. or,
The write control circuit 61 includes a detection circuit 6 for detecting a column direction position that changes when the sheet 16 is moved to or from a column.

The numerical value is displayed on the number display 60. In this case, the write control circuit 61 determines that if the push button 24a of the pen switch 24 is pressed three or more times at the same column direction dimension position, the data after the third press is determined to be data to be input to the next memory address. Therefore, writing to the same memory address in the creation pan memory 64 is not performed. Next, at the new column direction dimension position, the push button 24a of the pen switch 24 is set to 1 in the same manner as described above.
When pressed for the second and second times, the left knitting width direction dimension and right knitting width direction dimension are written and stored in the left dimension section and right dimension section of the next memory address of the creative pattern memory 64, respectively. Further, when the push button 24a of the pen switch 24 is operated only once at a new column direction dimension position and the position is changed to the next column direction dimension position, the write control circuit 61 controls the The knitting width direction dimension data is written and stored not only in the left dimension section but also in the right dimension section. Thereafter, by repeating the same pressing operation of the push button 24a of the pen switch 24, that is, the switch operation, the column direction dimension, left knitting width direction dimension, and right knitting width direction dimension are sequentially written and stored in each memory address of the creative pattern memory 64. be done.

First, a case will be described in which the information input device 12 is used to perform knitting based on a creative pattern.

Turn on the power switch (not shown) to supply power to the control circuit shown in FIG.
Plug in and connect to 6a. Then, the sheet 16 on which the outline line 41 is drawn is inserted into the sheet insertion hole 14 of the machine frame 13, and the tip of the pen 25 of the pen switch 24 passes through the horizontally parallel base line (composition starting point ROJ) on the sheet 16. The line passing through the starting point ROj and the main points PLl and PRl) is set so that it is located on the line passing through the starting point ROj and the principal points PLl and PRl. Thereafter, when the pen switch 24 is set to the start position 42 and the creation start key 55 on the computer 45 is pressed, the counters of the knitting width direction position detection circuit 68 and the row direction position detection circuit 69 are reset to the young count value 10J. 1 is set, the creation pattern memory 64 is cleared, and the row information signal of the row direction position detection circuit 69 at that time is given to the display control circuit 67 via the write control circuit 61, and the display control circuit 67 The tier direction dimension ROJ is displayed numerically on the tier number display 58. Thereafter, move the pen switch 24 to the right (in the direction of arrow 21) and insert the pen 25 into the outer shape line 4 on the sheet 16.
When the push button 24a is pressed (first press operation) at the main point PLl, the stage force direction position detection circuit 69 at that time is pressed.
The row direction dimension ROj, which is the row information signal, is stored in the row direction dimension section of the memory address RlJ of the creative pattern memory 64, and the knitting width direction dimension Rl8OJ, which is the knitting width information signal of the knitting width direction position detection circuit 68, is stored in the memory address RlJ.

When the push button 24a is pressed again (second press operation) by aligning the key point PRl with the main point PRl of the outer form line 41, the knitting width direction dimension R, which is the knitting width information signal of the knitting width direction position detection circuit 68 at that time, is determined.
3Oyo is the memory address RL of the creation pattern memory 64
At the same time, the knitting width information signal is stored in the temporary storage register 61a, the stored contents are given to the display control circuit 67, and the display control circuit 67 displays the knitting width on the right stitch number display 60. The direction dimension R3O is displayed numerically.

6 from left to right, or from right to left. For example, a Yang match that moves from main point PR6 to P
When moving to R7, first operate the push button 24a of the pen switch 24 according to the main points PL6 and PR6 at the same column direction dimension position, and then move to the main point PL7 (PL
6), operate the push button 24a of the pen switch 24 in accordance with PR7. In addition, when the main points on the left and right sides of the outline line 41 match like PLlO and PRlO, by operating the push button 24a of the pen switch 24 twice at the same position, the knitting width direction is the same. The dimensions are written to the left and right dimensions of the memory address. Sometimes, a symmetrical knitting pattern as shown in FIGS. 1 and 2 with dashed lines or as shown in FIG.
If the shape of the left half of the outline line matches the left half of Fig. 3, the main point PLl
~PL、Pen switch 2 according to each main point
It is sufficient to operate the push button 24a of the pen switch 24 three times at the position of the main point P[4, then operate it according to the main point PR7, and then press the push button 24a of the pen switch 24 at the position of the main point P[4]. Points PL8, PR8, PI-,,PR

After the information input operation using the information input device 12 as described above, when starting knitting work, stitch gauge information is then input. That is, from trial knitting using ground knitting yarn, stitch gauge information of the length per 60 vertical rows, for example, 135"? and the length per 40 horizontal rows, for example 120TS11, is obtained in advance, and the stitch gauge information is obtained using the number key 47 to Rl., r3J. and R5J, these are stored in the temporary storage register 61a of the write control circuit 61, and the storage contents of the temporary storage register 61a are given to the display control circuit 67, and the display control circuit 67 Stage number indicator 5
8 is displayed numerically as Rl35J instead of the above-mentioned column direction dimension (displays on the left and right stitch number indicators 59 and 60 disappear).

Thereafter, when the step gauge key 53 is pressed, the contents of the temporary storage register 61a are stored in the step gauge memory 65 as step gauge information R135J. Similarly, when the number key 47 is used to enter 1, R2, and 10 in sequence, this is stored in the temporary storage register 61a, and the stage number display 58 displays a numerical value of Rl2O. When pressed, eye gauge information Rl2Oj is stored in the eye gauge memory 66. Then, before and after inputting the stitch gauge information, the plug-in terminal 43a of the lead wire 43 is removed from the receiving terminal 46a of the computer 45, and replaced with the plug-in terminal 1 of the lead wire 11.
1a to the receiving terminal 46a and switch the creative basic changeover switch 56 to the 1 creative pattern side.
The outline data stored in the creative pattern memory 64 is selectively given to the arithmetic circuit 75 via the memory selection circuit 74, and then when the knitting key 50 is pressed to start knitting, the arithmetic circuit 75 is activated. Perform the following calculation operations. That is, when the edit start key 50 is pressed, the arithmetic circuit 75 sets the first row number, which is the content of the row number memory 80, to the initial stage r1, and this is given to the display control circuit 67. The display control circuit 67
causes the stage number display 58 to numerically display RlJ. At the same time, the arithmetic circuit 75 acts on the external pattern address memory 79 connected thereto to store the first memory address of the creative pattern memory 64, that is, the memory address RlJ, in the external pattern address memory 79, and also stores the same external pattern address. The creative pattern memory 6 corresponds to the memory address Rno and the next memory address Rn+L, which are the contents of the memory 79.
Input the non-memory type data of 4 and execute numerical operations. That is, a calculation value is calculated in advance, which is the basis for calculating the number of stitches in each row of knitting by determining it from the row gauge information and the row gauge information, which are the memory contents of the row gauge memory 65 and the row gauge memory 66. is stored in a calculation value register 76 connected to the calculation circuit 75, and the numerical calculation of the following equation is executed. 1 Left knitting width direction dimension at address Rno XLn 2 Right knitting width direction dimension at address Rno
The number of stitches XL(n), XL( n+1),
XR(n) and XR(n+1) are as follows, and the number of knitting stages Y(n) and Y(n+1) corresponding to the dimension in the row direction are as follows.
υυ.

For example, as mentioned above, when memory address 1 is stored in the external address memory 79, memory address 1 is stored in the external address memory 79.
However, assuming that the data stored in R2 is as shown in FIG.
The number of stitches required for knitting (3h) is calculated as follows, and the number of knitting rows corresponding to the row direction dimension Y1 is calculated as shown below.

Similarly, the left knitting width direction dimension XL2 (200?) and the right knitting width direction dimension XR2 (30?) at memory address R2j are determined.
The number of stitches required for knitting the fabric, and the dimension in the row direction (200
The number of knitting stages corresponding to 7 m) is calculated as follows, and if there is a fraction below the decimal point, it is always rounded up.

Then, the calculation value register 76 transfers the number of left and right stitches and the number of knitting stages obtained as described above to the next calculation circuit 7.
It is memorized until there is an input from 5. Thereafter, the arithmetic circuit 75 uses each calculated value stored in the calculated value register 76 and the contents of the row number memory 80 to determine the first stitch number in the first row number, which is the content of the same row number memory 80. For example, at the start of formation, the number of stages 1, which is the content of the number of stages memory 80, is set to 1L. Number of left stitches XR: Substitute the number of right stitches in the number of rows RY and round up if there is a fraction below the decimal point, and the values of XL and XR obtained from the result,
That is, the number of stitches on the left and right sides of the outer pattern line with reference to the center ROJ of the knitting machine main body 1, which in this embodiment matches the needle number as is, is connected to the arithmetic circuit 75. The number of stitches is stored in the stitch number memory 77.

The contents stored in the stitch number memory 77 are then given to the display control circuit 67.
is the forward/reverse changeover switch 5 that acts on the display control circuit 67.
7 to the 1 correct side, the value of the left stitch number information XL is numerically displayed on the left stitch number display 59, and the value of the right stitch number information XR is numerically displayed on the right stitch number display 60. Therefore, the operator must use the left eye number display 59 and the right eye number display 60.
Looking at the numerical values displayed respectively, that is, the needle number in this example,
For example, the left eye number display 59 is 1601 and the right eye number display 6 is
If 0 is displayed as 110, the previous sheet 1
Judging from the shape of the outline line 41 drawn in 6, in other words, in this example, by omitting the left and right needle number discrimination data, it is possible to determine whether it is the left needle number or the right needle number at any given time. Judging from the shape of the knitting work pattern, the knitting needles 3 between needle number 160 on the left side and needle number RlO on the right side are placed in the knitting standby position, and then the carriage 5 is slid to the left or right. and have them organize. Based on this sliding operation of the carriage 5, the carriage switch 9 generates a carriage passage signal every time the carriage 5 is operated leftward or rightward. In response to the signal, the number of one stage, which is the content of the stage number memory 80, is added and changed by one, and this is sequentially displayed as a numerical value on the stage number display 58 via the display control circuit 67. Then, the arithmetic circuit 75
When the number of stages, which is the content of the stage number memory 80, is changed, the first step is to check whether the changed number of stages is smaller than the value of Y(n+1) (number of stages) stored in the calculation value register 76. After determining this, a proxy calculation using the same equation as described above is performed on the condition that this is satisfied, and the stitch number information obtained thereby is stored in the stitch number memory 77. For example, if the changed content of the stage number memory 80, ie, the number of stages 1, matches Y(n+1), the arithmetic circuit 75 immediately acts on the external address memory 79 to change the stored content. By adding a certain memory address RnJ, for example, if memory address RlJ is stored, it is changed to memory address R2J, and in the same way as above, the creation pattern memory corresponding to memory address R2J and the next memory address R3 is added. 64 non-memory type data are input, numerical calculations are performed, and each memory address 12 and 13 is input.
After obtaining the number of stitches and the number of knitting rows for j, these are input into the calculated value register 76 and rewritten. Then, based on the stored content of the new calculation value register 76 and the content of the row number memory 80, ie, the number of one row, the stitch number information obtained by performing a substitute calculation using the same equation as described above is stored in the stitch number memory 77. to be memorized. Therefore, each time the operator slides the carriage 5 to the left or right, the operator checks whether or not there is a change in the numerical display on the left eye number display 59 and the right eye number display 60, and if there is a change. knitting needle 3 between the left and right needle numbers accordingly
is placed in the knitting standby position, and after performing the necessary addition/reduction operations, the sliding operation of the carriage 5 is performed. It should be noted that each time the arithmetic circuit 75 acts on the outer mold address memory 79 to change the memory address RnJ, which is the content thereof, the calculation circuit 75 changes the storage of the creative pattern memory 64 corresponding to the memory address Rno and the next memory address Rn+1. Input the contents and first select each memory address 1no,
The dimensions in the column direction of Rn+1 are compared, and if they match, or if the dimension in the column direction of memory address Rn+L is smaller, so-called skip control is performed to further act on the outer mold address memory 79. As a result, the memory address that is the contents of the external type address memory 79 is set to R.
L addition is performed, the memory address after the addition and the memory contents of the creative pattern memory 64 corresponding to the next memory address are inputted, and then the above-mentioned numerical calculation is executed, and the result is stored in the calculation value register 76. input. Therefore, in the storage contents shown in FIG. 7, when the contents of the outer mold address memory 79 are changed from R5 to R6, the column direction dimensions at memory addresses R6 and R7J are the same, so Immediately, the contents of the outer mold address memory 79 are changed to R7, and the results of calculations based on the contents of the creative pattern memory 64 corresponding to the memory addresses R7, J8, are input to the calculation value register 76. In the above manner, the main points PLlO and PRl of the outline line 41 are finally
O is reached, and the stitch numbers representing the same needle numbers are displayed on the left and right stitch number indicators 59 and 60, so that the left half of the front body of the cardigan based on the outer shape line 41, which is the original knitting work pattern, is displayed. When the knitting work is completed, knitting is performed by inputting the data of the knitting work type of the remaining right half of the cardigan in the same manner as described above. Sometimes, when knitting the front body of a bullover as shown in FIG. 5a, the outer shape line 41 of the right half in FIGS. Since it is symmetrical with respect to the outer shape line 41 of the section, the following operation is performed especially when dividing the knitted fabric into left and right parts and knitting them separately, that is, when knitting the left and right shoulder parts. That is, as mentioned above, after the completion of the knitting of the left shoulder portion, which was started at the beginning, among the knitting between the main points PL6 and PR6 based on the outline line 41, the computer 45
When the return key 51 is continued to be pressed, the arithmetic circuit 75 performs a subtraction operation on the 1st stage number, which is the content of the stage number memory 80, and a stage return is performed. In this case, the number of rows that are sequentially returned is numerically displayed by the row number display 58, and the number of stitches on the left and right of that number of rows is numerically displayed by the left and right stitch number displays 59, 60. Of course. When the 0-stitch number, which is the content of the stitch number memory 80, returns to the point corresponding to the main point PL6, that is, when the same stitch number data is displayed on the left and right stitch number displays 59 and 60, the return key 51 is pressed. When the pressing operation is released, the contents of the row number memory 80 are stopped, and when the contents of the row number memory are advanced using the feed key 52 so that the needle number data corresponding to P1-7 is displayed in the main direction, the arithmetic circuit 75 performs the above-mentioned calculation based on the contents of the stage number memory 80 at this time, and displays the left eye number display 59 and the right eye number display 60.
In this case, if the forward and reverse changeover switch 57 is switched to the 1st direction, the left stitch information will be displayed on the right stitch number display 60.
and the right stitch information is displayed on the left stitch number display 59. Therefore, the knitting needles 3 are knitted according to the numerical display, that is, the needle number, of these left stitch number display 59 and right stitch number display 60. By moving the carriage 5 to the selected standby position and sliding the carriage 5, it becomes possible to knit the right shoulder part, which is symmetrical to the left shoulder part, and knit the front body of the bullover. In addition, if the pressing operation of the return key 51 in the computer 45 is stopped in a short period of time, the arithmetic circuit 75 subtracts only one step from the 1 step number which is the content of the step number memory 80, and also presses the forward key 52 for a very short time. 1 of the stage number memory 80.
Only one stage is added to the number of stages, and when the return key 51 or the forward key 52 is pressed in combination, the arithmetic circuit 75 stores information in the middle stage number memory 80 while the key is being pressed. The number of stages is sequentially subtracted or added one stage at a time.

Now, a case will be described in which knitting is performed using basic patterns (outline data) stored in advance in the basic pattern memory 70 without using the information input device 12.

In this case, the outline line 71 as shown in FIG.
72, 73, etc., and enter its work number using the number key 47 of the electronic computer 45. As a result, the work number, which is a numeric signal input by the numeric key 47, is temporarily stored in the temporary storage register 61a of the write control circuit 61, and the temporarily stored work number is sent to the stage number display via the display control circuit 67. The numerical value is displayed at 58. Thereafter, when the work key 49 is pressed, the work number stored in the temporary storage register 61a is transferred to the work data memory 63.
will be remembered. Incidentally, in the row gauge memory 65 and the eye gauge memory 66, the row gauge information and the eye gauge information obtained by the trial knitting are stored in the same manner as described above. Then, when the creation basic changeover switch 56 is switched to the 1 basic pattern side, the memory selection circuit 74 selects the outer shape data of a large number of basic patterns stored in the basic pattern memory 70 from the work number stored in the work data memory 63. Outer mold data corresponding to the work number is selected and provided to the arithmetic circuit 75. Thereafter, when the compiling start key 50 is pressed to start compiling work, the arithmetic circuit 75
The calculation operation is performed based on the outline data of the selected basic pattern on the same principle as in the case of the outside form line 41 of the above-mentioned creative pattern, and it is possible to perform knitting work based on the basic pattern. be. Note that the auxiliary power supply circuit 81 shown in FIG. 8 is configured with, for example, a rechargeable nickel-cadmium battery,
It maintains the contents of the memory circuits 62 and 78 and prevents the contents of the memory circuits 62 and 78 from being volatilized even when the main power supply of the control circuit is turned off. When power is supplied to the circuit,
Charge your own auxiliary power source and wait for the next volatilization prevention action. When a power switch (not shown) is turned on and power is supplied to the control circuit, the arithmetic circuit 75 immediately performs an arithmetic function in connection with the power on state. Since the contents of the memory circuits 62 and 78 are all held as they were last time by the action of the auxiliary power supply circuit 81, the arithmetic circuit 75 executes the arithmetic operation based on the contents of each memory, and stores the result in the arithmetic value register 76 and Each stitch number is input into the stitch number memory 77 to restore the previous state. Therefore, even if you stop work and turn off the power switch during assembly, or if there is a power outage, when power is supplied again, the machine will be restored to its previous state when the power was turned off. , each display 58, 59 and 60
etc., the display will remain as before. As described above, according to this embodiment, the main points of the outer shape line 41 etc. of the knitting work shape created on the sheet 16 are connected to the pen switch 24.
By directly instructing and pressing the push button 24a, that is, operating the switch, the dimensions in the column direction and in the knitting width direction of the indicated main points are inputted as numerical data to the computer 45, and the created pattern memory 64 is sequentially inputted. Since an information input device 12 is provided to store the information in the
By simply operating the pen switch 24, the outline line of the knitting work pattern created by the person in the desired shape, size, etc. on the sheet 16 can be easily and reliably input into the electronic computer 45 as numerical data. With this method, a knitted work created in a desired shape, size, etc. can be knitted very easily.

Further, according to the present embodiment, the basic pattern memory 70 in which the computer 45 stores external pattern data of a large number of basic patterns of knitting work types and the information input device 12 input the external pattern data of knitting work patterns of creative patterns. A creative pattern memory 64 is provided to store the external pattern data, and the external pattern data is selectively transferred to the arithmetic circuit 7 by switching the creative basic changeover switch 56.
5, the knitting work can be knitted using either the basic pattern or the original pattern, which is extremely convenient.

In the above embodiment, the width rotating disk 33 is used to read the left and right knitting width direction dimensions, but instead of this, for example, a long width disk disposed across the front side of the sheet 16 may be used. A slit plate may be used. In this case, a reset switch and a switch for the counters of the knitting width direction position detection circuit 68 and the row direction position detection circuit 69 are provided at both the left and right ends of the slit plate. It is also possible to provide one.

Sometimes, in this example, when determining the main points of the outer shape line of the knitting work pattern drawn and created on sheet 16, sheet 1
6, and then set it on the information input device 12, but as you get used to it, you can leave the outline line as just the original curve and immediately indicate it with the pen switch 24 at the approximate position. However, it is sufficient for practical use.

In addition, in this example, the knitting width direction dimension in response to the first operation of the pen switch 24 at each column direction dimension position is stored in the left dimension section of each memory address, and the right dimension section in response to the second operation. Although it is configured to write and store data in
By further improving this and comparing the data of each knitting width direction dimension in response to the first and second operations, the left knitting width direction dimension is made into the left dimension part, and the right knitting width direction is corrected if necessary. The directional dimension may be written and stored in the right dimension section. In particular, in this example, in order to notify whether writing and memorization have been effectively performed by operating the pen switch 24, an electronic buzzer or the like may be added to emit a ping each time the pen switch 24 is operated, and may respond to each key operation. It is also possible to freely configure the electronic buzzer to sound every time the electronic buzzer is activated. The electronic computer 45 as the molding instruction device in this example operates using a DC power source stabilized by transformer rectification from an ordinary household AClOO line. It may also be used for purposes other than memory protection, such that it can be used as a power source for the entire control circuit.

Although the information input device 12 in this example only inputs the data of the outer shape line of the knitting work type, for example, it can draw pattern data as exemplified by the chain lines in FIG. The switching position etc. of the pen switch 24
By inputting the row direction dimension into a pattern position memory prepared in advance by instructing it so that it can be distinguished from the outer mold data, the arithmetic circuit 75 further stores the number of rows in the row number memory 80 that matches the row direction dimension. If the information is stored, the operator is free to notify the operator of this in an appropriate manner, for example by lighting a dedicated indicator lamp or sounding an electronic buzzer. In addition, in this example, the method for inputting numerical data and calculating the number of stitches at the main points of the outer form line is to Although the configuration requires setting the knitting width direction dimension of the left and right sides, for example, by inputting the main points of the left and right outline lines independently, the number of stitches can be calculated and controlled separately. As a result, in the case of a knitting work type as shown in FIG. 3, the number of operations of the pen switch 24 can be minimized. In addition, input the knitting width direction dimension including left and right discrimination data from the center RO of the needle bed, and then when displaying the number of stitches as a calculation result, for example, the needle number 100 on the left side is 1.
By displaying -100, and displaying 10 on the right side as 1+100, it is extremely easy to use and reduces erroneous operations. By the way, in addition to the electronic computer 45, the memory circuit 6
The contents of 2 are called up as needed and displayed on the stage number display 58.
Alternatively, it would be more convenient in practice if a call key and its control circuit were added to display confirmation on the left and right eye number displays 59, 60. In addition, the stitch information for each row of knitting determined based on the outer shape data that is the content of the creative pattern memory 64 can be output to, for example, a dot-type printer device, and the previous sheet 16 can be set thereon. Same sheet 1
If you print out the change in the actual knitting needles in addition to the outline line on 6, you will be able to understand the differences at a glance, and therefore, you can check the suitability of the information input before starting to knit the fabric. It is easy to judge and extremely convenient. The computer 45 in this example should be installed in a place where it can be easily observed by the operator, especially when displaying the stitch number, and should be installed in a place that can be easily observed by the operator, and should be installed in the center of the knitting machine body 1 as shown in FIG. However, it may also be installed so that it can be attached and detached using appropriate mounting brackets, for example, on a tension bar, or it may be installed in a manner that allows it to be attached or detached, for example, to a tension rod or the like. It may be installed by attaching it to a molded stand and freely adjusting the angle and direction, or it may be stored together with a pattern guide etc. in a foldable case, and when used, it can be used as appropriate, for example as a portable alarm clock. It is also possible to have a configuration in which the pattern guide is placed upright, and displaying the required work types on the pattern guide is arranged on the side.

Further, the carriage switch 9 in this example may be constructed as a dedicated unit as shown in FIG. Sometimes, the end connection terminal of the cord wire 11 (on the opposite side to the plug-in terminal 11a) may be inserted into the output terminal on the back side of the stage counter unit to ensure electrical connection. If the swing lever is also used to generate the carriage passage signal, it is extremely convenient since there is no need to equip the carriage 5 with a special magnet 10. Even if it is a knitting machine, if a carriage switch that generates a carriage passing signal in conjunction with the drive swing lever is built in nearby, and its output terminal is provided outside the knitting machine, it will be extremely practical. It becomes convenient.
In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and it goes without saying that it can be implemented with appropriate modifications within the scope of the invention. As described above, the present invention allows a worker to easily and reliably input the outer shape line of a knitting work pattern created into a desired shape and size as numerical data, and to obtain the desired shape and size. It is possible to provide a device for forming a knitted fabric using a knitting machine, which has the excellent effect of extremely easily knitting a knitted fabric created in the shape, size, etc.
